Witt posed an interesting scenario to one student, saying that if he were a garbage collector who never went to college, is it fair that his tax dollars finance the student's education — and the student hesitated at first but then finally replied "yes."

It also appeared that few, if any, students at the elite school understood why college tuition continues to skyrocket — or even knew that student loans can't be discharged in bankruptcy. But Witt filled them in.

But not every student was down with free college

Witt spoke to one student who said free college for all isn't such a hot idea — and that not everybody should go to college: "There's this, I guess, stigma that ... if you don't go to college you're like wasting your life or, like, not living up to potential. But I think it should be, like, an exception ... exceptional people going to college instead of, like, everybody going."
